see text Recumbirostra is a clade of tetrapods which lived during the Carboniferous and Permian periods.

They are thought to have had a fossorial (burrowing) lifestyle and the group includes both short-bodied and long-bodied snake-like forms.

An alternative clade called Tuditanomorpha is occasionally supported and includes many of the same taxa.

[14] Furthermore, the taxa that are often considered to be recumbirostrans have been found among amphibians (and not as a distinct clade) in some analyses.

[15] Below is a cladogram showing the phylogenetic relationships of recumbirostrans from Glienke (2012):[4] Microbrachis Pantylus Stegotretus Sparodus Cardiocephalus sternbergi Cardiocephalus peabodyi Euryodus primus Euryodus dalyae Pelodosotis Micraroter Rhynchonkos Eocaecilia Tambaroter Altenglanerpeton Batropetes Carrolla Quasicaecilia
